Anyone can help ? how can we do a conversion in order to convert raster from cassini to wgs84 ?
I'm not sure this question makes any sense. Cassini is a projection. WGS84 is a datum.
I'm new to this forum, and I tried responding a few minutes ago. I don't see my response though.
I was pointing out that Cassini is a projection, whereas WGS84 is a datum.
Perhaps you meant geographic WGS84? Unfortunately to really do it right you would have to know which datum your projection is in.
If you're working in Arc/Info, you would want a projection file something like this;
It won't work as is; you would have to specify parameters for your Cassini projection, including the correct datum.
